Copper‑Core 8.7/15kV XLPE‑Insulated PVC‑Sheathed Power Cable

Copper‑core 8.7/15kV XLPE‑insulated PVC‑sheathed power cable is a medium‑voltage power‑transmission cable specially designed for 15 kV‑class power‑distribution networks. Its conductive core adopts high‑purity copper conductor, featuring excellent electrical conductivity, low transmission loss and stable long‑term current‑carrying capacity. Cross‑linked polyethylene (XLPE) is selected as the main insulating material. After cross‑linking modification, polyethylene forms a dense and stable three‑dimensional molecular network, which greatly enhances insulation strength, heat‑resistance performance, anti‑ageing property and electrical stability, and can withstand long‑time operation under medium‑voltage load. The outer‑layer polyvinyl chloride (PVC) sheath serves as a mechanical‑protective barrier, effectively protecting the inner insulation and conductor from moisture, dust, sunlight ageing, slight mechanical abrasion and general chemical contamination. Benefiting from this multi‑layer composite‑structure design, the cable integrates outstanding high‑voltage electrical performance, reliable mechanical durability and good cost‑effectiveness, becoming an ideal power‑transmission solution for urban power grids, industrial parks and medium‑voltage engineering projects.

Strict quality‑management specifications are implemented throughout the whole manufacturing workflow. High‑quality oxygen‑free copper rods are drawn and stranded into compact‑structured conductors, ensuring stable load‑carrying capability. XLPE insulation is extruded uniformly around the conductor under precise temperature and pressure control, so as to eliminate potential defects such as bubbles, impurities and uneven insulation thickness which may cause partial discharge. After core‑stranding, the outer PVC sheath is extruded, cooled and shaped. Every finished cable undergoes a complete set of performance‑verification tests, including conductor‑resistance measurement, insulation‑resistance detection, partial‑discharge test, high‑voltage withstand test, sheath inspection and dimensional verification. These rigorous quality‑control procedures remove hidden dangers such as insulation breakdown and outer‑jacket damage, guaranteeing that each reel of cable can run safely and stably for a long‑term period in complex medium‑voltage power‑supply environments. This cable is mainly suitable for fixed‑installation medium‑voltage power‑transmission and distribution circuits. It can be laid inside cable trenches, tunnels, cable ducts, underground pipelines and overhead‑support routes, adapting to indoor, outdoor and semi‑exposed laying‑conditions without heavy‑mechanical‑impact risks.

This medium‑voltage cable delivers remarkable comprehensive performance in practical engineering applications. The XLPE insulating layer enables the copper conductor to maintain a long‑term allowable operating temperature of 90 °C, providing high‑capacity power transmission for medium‑voltage distribution networks. Its low dielectric‑loss characteristic reduces energy consumption during electric‑energy delivery. The PVC outer sheath possesses decent waterproof, dust‑proof and anti‑pollution performance for conventional industrial‑site environments. The compact cable‑structure facilitates transportation, field laying and terminal‑connection construction. With excellent anti‑ageing properties, the cable achieves a long expected‑service‑life under normal‑operation conditions, effectively lowering circuit‑renovation frequency and maintenance costs for project owners. It is widely applied for medium‑voltage trunk‑line power supply of industrial‑production zones, urban community power‑distribution loops, substation outgoing‑line circuits and auxiliary‑facility medium‑voltage transmission‑lines.

Our copper‑core 8.7/15kV XLPE‑insulated PVC‑sheathed power cables and the full spectrum of our cable‑product portfolio are extensively deployed in metallurgy, electric power, energy, chemical industry, construction, shipbuilding, transportation and many other industrial sectors, as well as a large number of national key infrastructure‑construction projects.

Within the metallurgical industry, these medium‑voltage cables are used for main medium‑voltage power‑supply trunk‑lines of smelting equipment, rolling‑production‑line distribution loops, raw‑material‑handling‑system wiring and auxiliary‑facility power‑transmission lines inside metallurgical plants. Large‑scale metallurgical workshops are equipped with high‑power continuous‑running production equipment, requiring stable medium‑voltage electric‑energy supply. Our 8.7/15 kV power cables deliver dependable power transmission for metallurgical‑production systems and support safe, uninterrupted industrial‑manufacturing operations.

In the electric‑power sector, this cable series plays a vital role in urban and rural medium‑voltage power‑grid renovation projects, substation 15 kV outgoing‑line circuits, power‑plant auxiliary‑equipment medium‑voltage distribution loops and regional power‑supply trunk‑lines. Urban medium‑voltage distribution networks cover wide‑ranging municipal zones, residential districts, commercial‑building clusters and industrial parks. The excellent high‑voltage insulation performance of XLPE ensures safe and stable power transmission for regional grids, reducing circuit‑fault incidents and improving the reliability of urban power‑supply networks.

For energy‑development projects, the cables are applied to on‑site medium‑voltage power‑distribution systems of photovoltaic‑power stations, wind‑farm internal medium‑voltage power loops, oil‑and‑gas‑field auxiliary‑equipment wiring and energy‑storage‑station medium‑voltage power‑supply circuits. New‑energy projects are usually constructed in open‑air zones with complex natural‑environment conditions. The robust structure of our copper‑core 8.7/15 kV XLPE‑insulated PVC‑sheathed cables meets field‑site laying requirements and provides stable medium‑voltage power‑transmission support for renewable‑energy‑generation facilities.

Chemical‑industrial parks deploy this cable type for medium‑voltage power‑supply circuits of production reactors, pumping‑station high‑power equipment, workshop power‑distribution loops and automated‑control‑system trunk‑line wiring. The general‑grade anti‑corrosion performance of the PVC outer‑sheath satisfies routine laying‑demands inside most chemical‑plant zones without highly‑concentrated corrosive‑gas environments, delivering reliable medium‑voltage electric‑power for chemical‑production workflows.

In the construction industry, the cables are widely used for medium‑voltage main power‑supply trunk‑lines of large‑scale industrial parks, underground medium‑voltage distribution circuits of commercial complexes, municipal‑engineering supporting‑power‑supply systems and underground‑garage heavy‑load power loops. Ship‑building and marine‑engineering projects select these cables for shore‑based dock‑facility medium‑voltage power‑distribution circuits and on‑land ship‑repair‑shop internal‑wiring systems, meeting land‑side medium‑voltage power‑transmission demands of marine‑industry facilities. The transportation industry makes full use of the cables for highway‑service‑area medium‑voltage power‑supply circuits, railway‑station auxiliary‑equipment distribution loops, traffic‑hub internal‑medium‑voltage power‑transmission lines and tunnel‑facility power‑supply wiring.
